BC RACING COILOVERS ZX SERIES - MERCEDES BENZ C-CLASS W205/S205 14-21
BC RACING COILOVERS ZX SERIES - MERCEDES BENZ C-CLASS W205/S205 14-21
The BC Racing ZX Series is built specifically for racing and intensive track use, offering a true 3-way adjustable damper system at a level normally seen only in high-end motorsport suspension. Each ZX kit provides independent adjustment of low-speed compression, high-speed compression, and rebound, allowing the chassis to be tuned with exceptional precision for different circuits, surfaces, and driving styles.
Unlike the inverted motorsport kits, the ZX Series uses an upright damper layout, allowing compatibility with a wider range of replacement upper mounts. The large external reservoir increases oil volume and helps maintain stable operating temperatures, while the use of ultra high-viscosity synthetic racing fluid ensures consistent performance during long stints, endurance sessions, or drifting competition.

Spring Rate Options
The ZX Series is designed purely for racing and competition use. The Recommended spring rate provides a strong baseline for circuit and drift setups, offering stable support for high grip levels and aggressive weight transfer.
Higher rates are available for cars running slick tyres, significant aero, or stiffened shells. Softer rates may be chosen for cars competing on low-grip surfaces or where mechanical compliance is strategically required.
If you need guidance on the best spring rate for your tyre choice, aero setup, or motorsport discipline, feel free to get in touch and we’ll help you select the right option.
